Do you have macro shots of the front and back of the card?


Do you have a voltmeter?

I do not have a voltmeter, but a voltage monitoring software will do?

both IC are on the front looks like.. GPUv is the 8pin IC just to the left of the cooler on front ... vMEM is the 8pin IC on the top right above the cooler.

 

**If you can please post the descriptions written on those IC's? I cannot make them out from the pic clearly.

A voltmeter is best, as software monitoring can be wrong. You can always do it slow, shade the resister with the pencil, test if your max clocks increase, and then shade again. Problem is that you won't know if you are giving it too much voltage.

I agree with cl3p20 that the vmem is the top right on the front, but I think the vgpu is on the top right on the back since it is right near the mosfets. Plus I can kind of make out a uP on the chip, which means it is a uPI Semiconductor chip (vrm controllers).

I think Nuke is right. The flow is right too.. starting with input cap/s [which are missing]->mosfets->inductors->output caps...That would mean both of your uPi's are for GPUv/vMEM.. and i cant find any info on them. Looking at the description of the RT controller.. i think it may just be for PLL or VTT. Its a adjustable IC though with limit of 1.8v . May have to try to tone out the pins and look for some 'reasonable' resistance levels to get an idea of how to mod those uPi's though...

 

*got a DMM?
